Still, on the topic of pronunciation, Wikipedia's audio clip of an Icelander saying "Eyjafjallajökull" is... well, it's a remarkable noise. Rhyme anything English with it, they'll crown you Poet Laureate or something. It sort of starts "Eyja-" and then I need a fish in my ear.

It's the way they can pronounce the double L at the end of a word, something I can only really do in the middle. It should be a bit like -tl (like certain Mexican place names) but I find it hard to do without a following vowel.

I'm quite used to the double (geminated?) consonants in Scandinavian languages, and I can imagine how it might be possible at the end of a word. The recording does sound like he's eating lutefisk instead of actually saying the word for 'glacier', though.
